Question:

i have a civic and the heat dnt wrk,theres a bubbling sound under dash and it over heats wen i leave it idlin?

i dnt kno wats wrong with it, it was fine a week ago but now the heat dnt wrk and theres a bubling sound under the dash, and wenever i leave it to idle for a while it starts to over heat, i need some advise plz

Answer:

My guess is your heater coreThe heater core would explain no heat and you should be seeing smoke coming out of your ventsThe bubbling sound would be the coolant leaking into your cabinSince there is no coolant it should be constantly overheatingIts possible that while driving the air is cooling your engine, but unlikelyA couple of costs: Heater cores are $20 - 40, installation is about $200That's on the cheap because if you've overheated the engine the cylinder head(Most likely aluminum) has warped and you will soon have a blown head gasketIf not? Well then consider the $250 a blessing.
